Functional Endoscopic Sinus Surgery (FESS)

Functional Endoscopic Sinus Surgery (FESS)

Endoscopic sinus surgery is a procedure used to remove blockages in the sinuses. This procedure is designed to improve the drainage of the sinuses and to improve airflow through the nose.

We develop sinusitis when the tissue lining our nose begins to swell and traps the mucus that would typically flow out of the nose. The trapped mucus can get infected with bacteria. FESS resolves the obstruction, congestion and improves the airflow and symptoms of sinusitis. A CT scan or nasal endoscopy determines if the procedure is required. FESS is minimally invasive, with no scarring as it is performed through the nostrils. Contrary to popular belief 80% to 90% people with chronic sinusitis feel the surgery ‘cured’ them. But FESS significantly eases one’s symptoms and limits how often your chronic sinus flares.

Note: Balloon Sinuplasty is used when simply enlarging a blocked sinus passage is sufficient and no cutting is required. On the other hand, FESS involves making incisions that are very precise in order to remove or minimize problematic bone or tissue within the nasal passages.

Frequently Asked Questions

FESS is a surgery for sinus disease. Sinusitis develops when the tissue that lines your sinuses begins to swell, trapping mucus which can cause bacterial infections. FESS is called as functional because it is done to restore how your sinuses work, or function.

Tissues can always grow back and may be required to be taken out after few years. Having said that, it is not, however, necessarily the case and the surgery allows your airways to open and become clearer. FESS eases your symptoms and limits how often your chronic sinus flares.
